The iconic image shows star Dustin Hoffman watching a woman put on a pair of hose, but all you can see of her is one leg, along with a hand and part of an arm. Most people have assumed the woman to be Bancroft.

"I think she was absent that day," quipped Gray, who started out working as a model before turning to acting. "I got paid $25. For one leg, that was good."

Gray, who appeared on Anderson Live alongside her Dallas co-star Patrick Duffy, also talked about how Larry Hagman's death will be addressed this season on their TNT drama.

"Beautifully and respectfully," Gray said, adding: "When he passed, the entire writing crew came in and it's like, 'Oh my gosh, what are we gonna do? How do we do it with the love and respect he deserved?' And they did it; it was amazing."

Hagman, who played J.R. Ewing, died Nov. 23. His final episode is scheduled to air March 11.
